The MIME (Multipurpose Internet Mail Extensions) ActiveX control allows users to set the necessary headers , add the desired attachments, and enter some body text. This object is useful for developing applications that send and receive mail messages having MIME and/or UUEncoded attachments. It can be used in conjunction with the SMTP, NNTP, and POP ActiveX controls.
在注册表中应该在:
HKEY_CLASSES_ROOT\MIME\DataBase\Content Type\<mime type>.
HKEY_CLASSES_ROOT\MIME\DataBase\Content Type\<mime type> Extension = <mime type ext>.
HKEY_CLASSES_ROOT\MIME\DataBase\Content Type\<mime type> CLSID = <player CLSID>.
HKEY_CLASSES_ROOT\<mime type ext>.
HKEY_CLASSES_ROOT\<mime type ext> Content Type = <mime type>.
HKEY_CLASSES_ROOT\CLSID\<player clsid>. Class ID of player. This is automatically added if you are using MFC or the ActiveX Designer Framework to create your control.
HKEY_CLASSES_ROOT\CLSID\<player clsid>\Control.
HKEY_CLASSES_ROOT\CLSID\<player clsid>\EnableFullPage\<mime type extension>.
在MSDN中有这样一个例子,介绍如何用ACTIVEX控件来实现MIME新类型的加入及播放。
